（Python）是否可以以這種方式使用列表作為參數？

Question

我想傳遞一個列表作為參數，並讓 Python 識別符合我正在尋找的標准的第一個列表項。 例如，而不是這樣：

sentence = "This is a sentence."

words = sentence.split()

for i in range(len(words)):
    if words[i].startswith("a") or words[i].startswith("e") or words[i].startswith("i") or words[i].startswith("o") or words[i].startswith("u") or words[i].startswith("y"):
        words[i] += "yay"

我會有這樣的事情：

sentence = "This is a sentence."

words = sentence.split()

vowels = ["a", "e", "i", "o", "u", "y"]

for i in range(len(words)):
    if words[i].startswith(vowels):
        words[i] += "yay"

謝謝

Answer 1

我會word[0] in vowels而不是嘗試使用str.startswith ：

>>> words = "This is a sentence.".split()
>>> vowels = ["a", "e", "i", "o", "u", "y"]
>>> [w + "yay" if w[0] in vowels else w for w in words]
['This', 'isyay', 'ayay', 'sentence.']

但是您可以通過在對any的調用中迭代vowels來使用startswith ：

>>> [w + "yay" if any(w.startswith(v) for v in vowels) else w for w in words]
['This', 'isyay', 'ayay', 'sentence.']
